Add reference docs generation using docma

[olle]

• Adding support for the minimal generate reference documentation
  using docma. Running npm run docs or npm run serveDocs will
  generate documentation from the source-files using docma.

  This branch still does not commit the generated ./docs output
  since it is still just used to try out and get a feel for how
  the generated documentation looks and behaves.

Please note that this is initially only for evaluation, whether the generated documentation is nice, pretty or good enough for use in for example a generated Github-page.

I think it's a good idea and it actually looks pretty nice! I played a bit with jsdoc and found that I could not get typedefs to show up properly with docma (see https://devhints.io/jsdoc for an example). Is it something we need (right now)?

Looks nice indeed!

@stwa Typedefs looked okay for me at first glance, what issues did you find?

I like the look-and-feel a lot. At the moment there's not that good support for a regular modular JS project though - everything is global and modules are not picked up by default etc.

I guess it's up to us to find the right way to do jsdoc, and tweak the configuration, if we want to move forward with this rendered.

I suggest we do similar branches for other tools too.
